'get' do not provide the name of outports for some subsystems

I came across a problem with get function. For some subsystems these lines below do not provide the name of port of subsystem, even there is one, and there is name.

connected_inports_handle = get_param(block_of_interest,'PortHandles');
lineHnd = get(connected_inports_handle.Inport(i),'line');          
SubName = get(lineHnd,'SourcePort');% get source port number of sub
SubHnd = get(lineHnd,'SrcBlockHandle');% get source block i.e Subsystem
OPName = get(find_system(SubHnd,'BlockType','Outport'),'Name');% get all outport name of subsystem

For some subsystems OPNAME = [], for some it is correct, e.g. [out1, out2] etc.

Can you paste here output of by adding this line in code

SubHnd =get(lineHnd,'SrcBlockHandle'); Subname = get(SubHnd,'Name');

This ouput is the name of the subsystem.

[Chetan Bhavsar]

Only one subsystem name or 2 ? As you said line going to two subsystems.

Can you share model or recreate dummy issue model and share here.

[Ewela]

Now I am working on the simple example in order to be understood and I will upload the dummy file. As you said it will be better.

[Ewela]

It works on the dummy model, but do not want to work on orginal file. I try to investigate the issue to be precise in issue definition.

Don't know if it makes a difference, but shouldn't those calls to get() really be calls to get_param()? Is that a documented use of get() ?
